If the STNAMEL function
returns a value to a variable that has not yet been assigned a length,
by default the variable is assigned a length of 20.
The STNAMEL function
converts a two-character state postal code (or world-wide GSA geographic
code for U.S. territories) to the corresponding state name in mixed
case.
Note: For Version 6, the maximum
length of the value that is returned is 200 characters. For Version
7 and beyond, the maximum length is 20 characters.
